Hey there! We've found the following might help you get unblocked faster:

• 🧵 Webhook -> HTTP Request (POST) Fails in a New Workflow
• 🧵 Outbound DNS / HTTPS to api.telegram.org failing — Telegram bot can't set webhook or poll
• 🧵 PayPal API Requests Blocked with 403 (Varnish 54113)

If you find the answer from one of these, please let us know by solving the thread!

Have you tried manually curling the HTTP URLs via container ssh (and/or enforcing IPv4)? Chances are, it’s trying to make outbound requests via IPv6, which isn’t supported as of now.

No, havn't. Please disable IPv6 or force IPv4 for outgoing requests from the n8n container (HTTP to api.kie.ai), requests are currently stuck without a response.
